How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want maximum noise blocking for sleep, swimming and loud events, choose Mack's Pillow Soft Silicone; if you need to take the edge off annoying noises while still hearing your alarm, your phone or your kids, choose FLARE AUDIO Calmer Night.
• Mack's Pillow Soft Silicone — biggest strength: moldable silicone putty that seals to the unique contours of any ear, with a stated Noise Reduction Rating of 22 dB (US) and a Single Number Rating of 30 dB (EU). It genuinely blocks sound.
• Mack's Pillow Soft Silicone — biggest trade-off: it's a putty you shape and press in yourself. It's a blocking earplug, so you'll also muffle alarms, phones and voices — and it isn't the kind of thing you'll want to wear all evening while chatting.
• FLARE AUDIO Calmer Night — biggest strength: it's explicitly an earplug alternative. It reduces your stress response to harsh frequencies without blocking sound, so you stay connected to the room around you.
• FLARE AUDIO Calmer Night — biggest trade-off: it does not block noise. If you need quiet, not calmer, it won't get you there — and the standard size is designed to fit roughly 90% of ears, not all.
• Choose Mack's if you want real attenuation for snoring spouses, swimming, concerts, travel or studying. Choose Calmer Night if you want a more relaxing evening and night while remaining aware of alarms and family.
Mack's Pillow Soft is the original moldable silicone putty earplug, and the design is the whole point. Instead of a rigid plug with a fixed tip, you warm a blob of soft silicone in your fingers and press it over the opening of your ear canal, where it molds to whatever shape your ear happens to be. That's why it's comfortable in a way that many fixed-size plugs aren't: there's no tip pushing into the canal, no pressure point you have to "get used to." You shape the seal yourself, and you re-shape it until it feels right. The stated ratings are 22 dB NRR under the US standard and 30 dB SNR under the EU standard — real attenuation numbers, which is the key contrast with Calmer Night.
The use-case list is unusually broad, and it's broad because it blocks: sleeping, snoring, swimming, bathing, studying, travel, loud events, concerts, flying, motorcycling. Mack's specifically notes lab testing showing it helps relieve airplane ear pressure and pain, and the brand positions itself around swimmer's ear prevention — it's safe for use with ear tubes and after ear surgery, and it's used as the official earplugs of USA Swimming. The putty is non-toxic, non-allergenic and waterproof, and it's made in the USA. If you're the person lying awake next to a snorer, this is the tool built for that exact job.
Who should buy it: swimmers and surfers worried about water in the ear, frequent flyers, concert and motorcycle riders, students in noisy dorms, and anyone whose main problem is a loud bedroom. Who should skip it: anyone who needs to hear an alarm, a baby monitor or a phone overnight, and anyone who dislikes the feel of putty in their ears. It's also a consumable — you press it into shape, it picks up oils and lint, and 12 pairs is a working supply rather than a permanent one. If you want a single pair you keep forever, the design works against you.
Calmer Night is a fundamentally different product, and it's worth being blunt about that: Flare calls it an earplug alternative, not an earplug. It does not block sound. What it does is sit in the ear and change how sound reaches you — Flare's description is that sound is accurately directed into the ear, reducing stressful frequencies so you can focus on the sounds you want. In practice, the harsh, grating edge of a noise gets softened while the information in it stays. You still hear the alarm. You still hear your phone. You still hear your children. They're just less abrasive.
That's a very specific benefit, and it maps to a specific person. If you're sound-sensitive — Flare explicitly calls out neurodivergent conditions including ADHD, autism and dyslexia — the problem often isn't volume, it's the quality of the sound. A refrigerator hum, a partner's breathing, traffic outside, a TV through a wall. Full blocking earplugs solve that by cutting you off, which has its own cost: isolation, missed alarms, the unsettling feeling of not knowing what's happening around you. Calmer Night is designed for people who find that trade unacceptable.
Physically, it's tiny — the product dimensions are roughly 0.43 x 0.51 x 0.83 inches, and it weighs about a gram, which is why Flare can claim it's comfortable enough to wear through the night. It's soft-touch silicone, reusable, white, and comes with a carry pouch, a user guide and recyclable packaging. Sizing is the one real caveat: the standard size is stated to fit 90% of users, and Flare says you should only pick the Mini if standard-size earphones don't fit you even with the smallest tips. The technology is patent pending and Flare notes independent testing by the Institute of Sound and Vibration Research.
Who should buy it: light sleepers bothered by specific annoying sounds rather than dangerous volume, people with sensory sensitivity, shift workers who must hear an alarm, and parents who can't afford to be deaf to a crying child. Who should skip it: anyone who needs genuine noise reduction — a snorer at full volume, a loud jobsite, a flight you want to sleep through. For those jobs, Calmer Night simply isn't the category of product you're shopping in.
• Best for actual noise blocking → Mack's Pillow Soft Silicone. A stated 22 dB NRR is attenuation; Calmer Night is designed not to attenuate.
• Best for hearing your alarm while sleeping → FLARE AUDIO Calmer Night. It's built so you still hear alarms, phones and children, just with the harsh edge taken off.
• Best for swimming and water protection → Mack's. Waterproof putty, safe with ear tubes, positioned around preventing swimmer's ear.
• Best for sound sensitivity and neurodivergent users → Calmer Night. Flare designed it around reducing your stress response to noise, and names ADHD, autism and dyslexia as the conditions it can help.
• Best for flying → Mack's. It's lab tested specifically to help relieve airplane ear pressure and pain.
• Best for all-evening wear and conversation → Calmer Night. You stay connected to the room; with Mack's you're sealed off.
• Best for a snoring partner → Mack's. Blocking is the only thing that solves that problem.
• Best for a reusable, keep-it-in-your-pocket pair → Calmer Night. It's a single reusable pair with a carry pouch, where Mack's putty is a consumable you'll use up.
My Verdict
No. Flare is explicit that it's an earplug alternative that reduces your stress response to annoying noises without blocking sound. Mack's blocks; Calmer Night softens harsh frequencies while keeping sound audible.
You can — it's designed for sleeping and it's soft and moldable. But it's putty, so it collects oils and lint and needs replacing over time, which is why it comes as a 12-pair supply rather than a permanent pair.
Flare states the standard size fits 90% of users. The guidance is to choose the Mini only if standard-size earphones don't fit you even with the smallest tips. If you're in that 10%, size down.
They're different products, so compare by use, not by unit. Mack's gives you a multi-pair supply of blocking putty for occasions where you need quiet; Calmer Night gives you one reusable pair for ongoing all-night wear.
